One thing that I think is at the heart of all this, is players not wanting to lose all that they have put into the game.
You can never lose that.
It is a part of your history that you will always have. That history is what makes you the PERSON you are right now. Rejoice in that, think fondly of those memories.
If you are better off putting down the game for a period of time, then do that. If it's a better game down the road, then come back to it to find that level of entertainment that you think is worthwhile.
